Perhaps CAHA felt that the B'Hawks were demonstrably better than the 8 teams they selected for Flight 2? I am not a big fan of the Jamboree (in part because it places too great a premium on CAHA getting the match-ups for the two pre-set rounds right), but coming out of the Jamboree I had the B'hawks at 7, even if they were not playing what I thought of as an AA style of hockey.
At the time, I thought there was a noticeable gap between the B'hawks and the top 6 teams, but that the Wave or D2 were more likely to be a bubble team in a larger Flight 1. After last weekend's games, I suspect that the differences in the teams from top to bottom might be smaller than I thought last week and that the dividing point may be between 4 and 5.
As an aside, I think K2 and D2 are both very interesting teams. I like their upside and dislike a system where one of them is necessarily eliminated from the playoffs before a single regular season game has been played.
